To all whom it may comm.-

Be it known that I, MARIUs J. \Vrsm', a States, and resident of Racine, in the county of Racine \Visconsimhave invented certain new and useful Improvements in Phonograph Horns; and I do hereby declare that the followin is 1zzifull, clear, and exact description thereo it lnis for'its object to provide an amplifying tone horn for such instruments having an attachment whereby the tone is modified orsottened to absorb the 'lnetalliosound'or vibrationsyfof the instrument.

provide, in connection with the standard therewith similar to the sore The specific object of my invention is to type of tone horn, a compartment having a scroll vent therein and a 0st associated ls and post of a violin, this compartment being gradually increased in size from the intake neck of the horn to the mouth thereof, and being otherwise closed.

With the above objects in view, my inventionconsists in certain peculiarities of construction and combination of parts as are hereinafter set forth with reference to the accompanying drawing and subsequently claimed.

In the drawings Figure 1 represents a sectional elevation of a horn having an attachment at its hottom portion in accordance with my invention and Referring b -YA represents "thereof; The

horn has spaced therefrom '4, which wall is merged into the bottom wall Figure 2 is a plan view of the same with arts broken away and parts in section as indicated by, the line 2'-2 of Figure 1.

The top wall is also provided with an opening D, towhich is connected the restricted neck 1 of a phonograph horn, which horn is curved forwardly and gradually. increased in' dimensions to form a bell-shaped mouth 2, that is merged ihto'the front wall about the opening 0.

an auxiliary wall near the neck portion 1 of the horn. From this point the auxiliary wall with relation to her 5, increasing indimensions' and State of invention refers to phonographs, andmain bottom wall 3 of the 1922. Serial No. 572,719.

the main bottom wall 3, is gradually flared therefrom to form a compartment or chamfrom the neck of the standard horn to its mouth. The walls-3 and t at the mouth of the-horn are connected by a lip 6,,whereby the auxiliary compartment or chamber is closed.

The auxiliary in the form of a double scroll 7, similar to that usually employed in connection with violin bodies, and between the scroll slots .there is placed a vertical sounding post 8,

which ost bonnects the auxiliary wall and the main bottom wall 3, and serves, in connection with the scroll vents in the compartmerit, to soften the tone emitted from the horn, similar to the principles involved in a violin body. a

' It is understood that while no mention has been made of the material from which the horn is manufactured as a whole, obviously the same is composed of wood or other fibre, as such material has been found in practice to produce the most satisfactory results.

IVhile I have shown and described one simple exemplification of my invention, in all of its details, it is understood that I may.

the outerend of the horn is approached, a member closing the space between the aper-- 'ttired wall and the auxiliary wall and located adjacent the outer end of the horn, and a support between said auxiliary and apertured walls and contacting with said apertured wall at a point between said apertures. In testimony that I claim the foregoing I have hereunto set my hand at Racine, in the county of Racine and State'of WVisconsin.
